Node and method for service specific management

ABSTRACT

Example embodiments are presented herein service session management based on service specific data and a user subscription. Some example embodiments may comprise a user equipment, and corresponding method therein, for monitoring an internet or network access by an identified application. Upon detection, the user equipment may be configured to send service specific data associated with the identified application to an enhanced application server. The enhanced application server may manage a service session based on the service specific data and the user subscription. The management of the service session may allow for a differentiated delivery of service for certain applications.

BACKGROUND

In a typical cellular system, also referred to as a wireless communications network, wireless terminals, also known as mobile stations and/or user equipment units communicate via a Radio Access Network (RAN) to one or more core networks. The wireless terminals can be mobile stations or user equipment units such as mobile telephones also known as “cellular” telephones, and laptops with wireless capability, e.g., mobile termination, and thus can be, for example, portable, pocket, hand-held, computer-comprised, or car-mounted mobile devices which communicate voice and/or data with radio access network.

The radio access network covers a geographical area which is divided into cell areas, with each cell area being served by a base station, e.g., a Radio Base Station (RBS), which in some networks is also called “NodeB” or “B node” and which in this document also is referred to as a base station. A cell is a geographical area where radio coverage is provided by the radio base station equipment at a base station site. Each cell is identified by an identity within the local radio area, which is broadcast in the cell. The base stations communicate over the air interface operating on radio frequencies with the user equipment units within range of the base stations.

In some versions of the radio access network, several base stations are typically connected, e.g., by landlines or microwave, to a Radio Network Controller (RNC). The radio network controller, also sometimes termed a Base Station Controller (BSC), supervises and coordinates various activities of the plural base stations connected thereto. The radio network controllers are typically connected to one or more core networks.

The Universal Mobile Telecommunications System (UMTS) is a third generation mobile communication system, which evolved from the Global System for Mobile Communications (GSM), and is intended to provide improved mobile communication services based on Wideband Code Division Multiple Access (WCDMA) access technology. UMTS Terrestrial Radio Access Network (UTRAN) is essentially a radio access network using wideband code division multiple access for user equipment units (UEs). The Third Generation Partnership Project (3GPP) has undertaken to evolve further the UTRAN and GSM based radio access network technologies. Long Term Evolution (LTE) together with Evolved Packet Core (EPC) is the newest addition to the 3GPP family.

Policy and Charging Control (PCC) was originally introduced in 3GPP standards as a mean to secure resources in the access network mainly for dynamic services (such as IMS), but also to control resource consumption for regular Internet services (P2P-traffic, web-browsing, FTP etc) and to enable Flow Based Charging (FBC).

Although the original goal with PCC has since long time been completed in 3GPP, there is still a lot of activities ongoing in standards enhancing the PCC framework with add-ons. The new functions amended to the PCC architecture have shifted the role of the PCRF from something that was originally just a requirement for IMS into a more fundamental system element.

SUMMARY

A need exists for operators to be able to have the capabilities to reach agreements with service provides (e.g., of OTT services) in order to provide a different service delivery compared to competitors. Current systems do not provide an efficient way of differentiating services. Thus, at least one object of some of the example embodiments provided herein is to provide such a system and method for service differentiation in an accurate and efficient manner. This type of service delivery may have the example advantage of providing a better quality of service with differentiated charging and quality of service requirements. Another example advantage is the ability to accurately monitor all outgoing and incoming traffic associated with an identified application. A further example advantage is that the example embodiments present a scalable method of service differentiation. Another example advantage is load reduction on gateway nodes as there is no longer a need to perform heuristic detection.

Thus, some of the example embodiments may be directed towards a method, in a user equipment, for providing service specific data for service session management. The method comprises monitoring an identified application. The method also comprises detecting a start of the identified application, where the identified application utilizes an internet or network during operation. The method further comprises sending service specific data associated with the identified application to an enhanced application server for service session management.

Some of the example embodiments may be directed towards a user equipment configured to provide service specific data for service session management. The user equipment comprises processing circuitry configured to monitor an identified application. The processing circuitry is further configured to detect a start of said identified application, where the identified application utilizes an internet or network during operation. The user equipment further comprises radio circuitry configured to send service specific data associated with the identified application to an enhanced application server for service session management.

Some of the example embodiments may be directed towards a method, in an enhanced application server, for service session management of an identified application. The method comprises receiving, from a user equipment, service specific data associated with an identified application. The method also comprises managing a service session of the identified application based on the service specific data and a user subscription.

DETAILED DESCRIPTION

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular components, elements, techniques, etc. in order to provide a thorough understanding of the example embodiments. However, it will be apparent to one skilled in the art that the example embodiments may be practiced in other manners that depart from these specific details. In other instances, detailed descriptions of well-known methods and elements are omitted so as not to obscure the description of the example embodiments. The terminology used herein is for the purpose of describing the example embodiments and is not intended to limit the embodiments presented herein.

In order to provide a better explanation of the example embodiments presented herein, a problem will first be identified and discussed. FIG. 1 provides an example of a communication network 100. As shown in FIG. 1, a user equipment (UE) 101 may be in communication with a Universal Terrestrial Radio Access Network (UTRAN) 103, an Evolved UTRAN (E-UTRAN) 104, or a GSM Edge Radio Access Network (GERAN) 102 subsystem in order to access communication to an operator or application server 105. In gaining access to the operator or application server 105, the UTRAN/E-UTRAN/GERAN subsystem 102-104 may be in communication with a General Packet Radio Service (GPRS) subsystem 107 or an Evolved Packet Core (EPC) subsystem 109. It should also be appreciated that the network may further comprise a WiFi subsystem, although not illustrated in FIG. 1.

The GPRS subsystem 107 may comprise a Serving GPRS Support Node (SGSN) 111, which may be responsible for the delivery of data packets to and from the mobile stations within an associated geographical service area. The SGSN 111 may also be responsible for packet routing, transfer, and mobility management. The GPRS subsystem 107 may also include a Gateway GPRS Support Node 113, which may be responsible for the interworking between the GPRS subsystem 107 and the operator or application server 105.

The EPC subsystem 109 may comprise a Mobility Management Entity 115, which may be responsible for idle mode UE tracking, paging procedures, and attachment and activation processes. The EPC subsystem may also comprise a Serving Gateway (SGW) 117, which may be responsible for the routing and forwarding for data packets. The EPC subsystem may also include a Packet data network Gateway (PGW) 119, which may be responsible for providing connectivity from the user equipment 101 to the operator of application servers 105. Both the SGSN 111 and the MME 115 may be in communication with a Home Subscriber Server (HSS) 121, which may provide device identification information, an International Mobile Subscriber Identity (IMSI), etc. It should be appreciated that the EPC subsystem 109 may also comprise a S4-SGSN 110, thereby allowing the GERAN 102 or UTRAN 103 subsystems to be accessed when the GPRS 107 is replaced by the EPC 109.

The network may further comprise a Policy and Charging Rules Function (PCRF) 114 which may be in communication with the GGSN 113, the PGW 119 and the application server 105. The PCRF 114 encompasses policy control decision and flow-based charging control functionalities.

Often operators have an interest in being able to have the capabilities of reaching agreements with service providers in order to provide a different service delivery compared to competitors. Examples of such service providers may be providers of services which require network or internet access. Such a provide may be an Over The Top (OTT) service provider. An OTT service is a service which does not belong, or is not under the control, of the operator. Examples of such services may be Youtube™ or Skype™.

In providing a differentiated delivery of service, traffic associated with the service should be identified. One current method of such traffic identification is utilizing a different APN per application that requires a special service delivery. There are several problems with this approach. First, a terminal must be configured to use a different APN per application. This is not feasible if different QoS or charging requirements are to be applied to different subscribers. Furthermore, the use of multiple APNs requires multiple PDN connections and therefore multiple IPs. Thus, such a solution is not scalable.

Another example of a current traffic identification technique is the use of an Rx interface from the application server to the operator PCRF. The main drawback to this solution is that this implies that all application servers should be connected with all the PCRFs of all operators they have an agreement with. It should be noted that there may be hundreds of application servers for a single application. This solution is extremely costly to deploy.

Another example of a current traffic identification technique is the use of deep packet inspection. In many cases, the traffic needs to be identified through heuristics as the protocol is not public. This is, by definition, not accurate and therefore not very suitable if there is a commercial agreement. On the other hand, the service might change clients and protocol quite often, making the detection useless until a new signature has been delivered.

Thus, example embodiments are presented herein which enhance the communication between a user equipment and the network for identified applications. Such identification of the applications may be provided in an efficient and accurate manner. According to some of the example embodiments, traffic, associated with an application identified to receive a differentiated service, may be identified through the use of an entity or application (referred to herein as an enhanced application) which may reside on the user equipment. The enhanced application may monitor when the identified application initiates a communication on the network. Once the initiation occurs, the enhanced application may send information regarding the session to a server or node in the network. The server or node which receives such information will be referred to herein as an enhanced application server. The transmitted information may be used for enhanced traffic detection according to some of the example embodiments. Once the traffic has been identified on the core network, it may be treated in a differentiated way. It should be appreciated that the enhanced application server may comprise the same functionality as the application server 105 of FIG. 1, and therefore has been assigned the same reference numeral.

Table A below illustrates a messaging sequence, according to some of the example embodiments. The different messages illustrated in Table A will be addressed according to their corresponding line number. It should be appreciated that Table A is merely an example implementation and any other implementation or messaging within the scope of the example embodiments may be applied.

According to some of the example embodiments, the user equipment may first send an IP-CAN session establishment message to a gateway node (line 1). It should be appreciated that the term gateway node may comprise a PGW, SGW, SGSN, GGSN, etc. The gateway node may thereafter send a Gx CCR (INITIAL_REQUEST) message to the PCRF featuring the example information elements listed in Table A (line 2). The PCRF may thereafter select a profile for the user and decide which services or programs should be monitored or the identity of the enhanced application (line 3). The PCRF may thereafter send a Gx CCA message to the gateway node featuring the identity of services or programs which are to be monitored and/or the identity of the enhanced application (line 4). It should be appreciated that Table A provides that such programs are OTT programs, however, the example embodiments may be applied to any program or service which utilizes the internet or network. Thereafter, the gateway node may send a session response message to the user equipment (line 5).

Once a start of the enhanced application is detected (line 6) the user equipment may send an application or authentication request to the gateway node (line 7). The gateway node may insert identifying information in the request (line 8). The gateway node may further forward the request to the application server (line 9). The application server may authenticate the request and/or the authenticity of the enhanced application (line 10) and send results of the authentication to the gateway node (line 11). The gateway node may insert the services or applications to be monitored based on ADC rules which may be downloaded (line 12). The gateway node may thereafter send an application or authentication response to the user equipment (line 13).

Thereafter, the enhanced application may begin to monitor the services or applications which have been identified by the gateway, PCRF, and/or application server (line 14). The user equipment and/or enhanced application will thereafter detect once the identified service or application starts (or makes an internet or network access) (line 15-16). The user equipment and/or enhanced application will thereafter send an application request message to the gateway node indicating that the identified or monitored service/application has started (lined 17). According to some of the example embodiments, the request may comprise information elements such as various identifiers and a 5-tuple, as shown in Table A. It should be appreciated that any other information element may also be comprised in the response.

TABLE A

The gateway node may then map the service or application with predefined ADC rules (line 18) and create filters for the corresponding predefined ADC rule out of the received 5-tuple (line 19). Thus, filters for detecting the traffic associated with the identified application/service may be provided. By using the 5-tuple information, the traffic may be more accurately detected. It should be appreciated that the use of the 5-tuple information is provided as an example. Any other form of identifying information may be utilized to provide more accurate traffic detection filters.

Upon the creation of the filters, the gateway node may send an application request to the application server (line 20). The user equipment may also start sending payload information to the gateway node (line 21). With the use of the newly established filters, the gateway node may start to filter and identify the traffic associated with the identified application (line 22). The gateway node may thereafter send a report to the PCRF on such detection (line 23). Thereafter, the PCRF may select appropriate QoS and charging parameters for the user and identified service or application (line 24). The PCRF may thereafter send the selected parameters to the gateway node (line 25) which will enforce such parameters (line 26), thus providing the differentiated service for the traffic associated with the identified application.

Table B, provided below, illustrates yet another example messaging diagram incorporating the example embodiments presented herein. As shown in Table B, the user equipment, gateway node, and PCRF may utilize similar establishment methods as illustrated in lines 1-9 of Table A (lines 1-9). However, one difference with the example embodiment illustrated in Table B is that it is the application server, not the PCRF, which selects the applications or services to be monitored (line 10). Once the application server selects the services or applications to be monitored, the application server may send a query message to the PCRF (line 11). The PCRF may thereafter send a query response with the applications which may be monitored (line 12). Thereafter, the application server may send an authentication message to the user equipment with a list of services or applications which should be monitored (line 13).

Thereafter, the user equipment or enhanced application may monitor and detect an internet or network access attempt by the identified application, in a similar manner as was performed in Table A (lines 14-16). Once a detection has been made, the user equipment or enhanced application may send a notification to the application server (line 17). The notification may comprise various information elements providing information to assist in enhanced traffic detection. It should be appreciated that the information elements in Table B are provided merely for the purpose of explanation. Any other information element may also be utilized.

The application server may inform the PCRF of the detection by sending a request message which may feature the provided information elements (lines 18-19). The PCRF may send an acknowledge message to the application server and select appropriate QoS and charging parameters for the detected and identified application or service (lines 20-21). The PCRF may thereafter send a request with dynamic PCC rules to the gateway node and the gateway node may thereafter send an acknowledgement (lines 22-23). The gateway node may thereafter install the PCC and selected QoS and charging policies, thereby providing differentiated service for the identified application or service.

The example embodiments of Table A and Table B illustrate an application server which is a separate network entity. It should be appreciated that the functionality of the application server may also be included in the gateway node, the PCRF, or any other network node.
